Mario and Courtney waited until the delivery date to learn the baby's sex, and Mario told Extra, "We are so overjoyed. What an amazing, wonderful and overwhelming experience to welcome our daughter into the world."

The couple met while costarring in Broadway's A Chorus Line, and this is the first child for both of them. Congrats!
